It is recommended that administrators running netatalk check for an updated version of the software for their operating system. Revision History: January 30 2009: Debian have revised to correct an error January 16 2009: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - -------------------------------------------------------------------------- Debian Security Advisory DSA 1704-2 security@debian.org http://www.debian.org/security/ Nico Golde January 30th, 2009 http://www.debian.org/security/faq - - -------------------------------------------------------------------------- Package : netatalk Vulnerability : arbitrary code execution Problem type : remote Debian-specific: no CVE ID : CVE-2008-5718 Debian Bug : 510585 The update in DSA 1704-1 was incomplete as it missed to escape a few important characters which enabled an attacker to overwrite arbitrary files. It was discovered that netatalk, an implementation of the AppleTalk suite, is affected by a command injection vulnerability when processing PostScript streams via papd. This is leading to arbitrary remote code execution. Note that this only affects installations that are configured to use a pipe command in combination with wildcard symbols substituted with values of the printed job. For the stable distribution (etch) this problem has been fixed in version 2.0.3-4+etch2. For the unstable distribution (sid) this problem has been fixed in version 2.0.4~beta2-1.1. We recommend that you upgrade your netatalk package. Upgrade Instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given at the end of this advisory: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration. Debian GNU/Linux 4.0 alias etch - - ------------------------------- Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
